DOORSTOIE.

Application filed December 15,

7 0 all whom it may concern:

it known that I, ARTHUR CLARKE SAR- onan'r, a citizen. of the United States of America, and a resident of rlgawam, in the county oi i-lampden and State of Massachusetts, have invented a new and useful Doorstep, oi. which the following is a specification.

My in vention'relates to improvements in devices for holding doors in open position, and is designed especially for use in connection with large and heavy, outwardly-swinging doors,.such as those used in garages, and consists essentially of a swivel member sup-. ported usually from the top of a door frame of casing, which member is perforated and equipped with an oscillatory latch and a spring-pressed pin or plunger, and a latchand plungerengaging member pivotally connected with the door, and operating in or through said firstnamed member in operativcrelation to said latch and plunger, the latter being adapted to cooperate with said latchand plunger-engaging member to assist in retaining the same in engagement with said latch, together, with such other parts and members as may be necessary or desirable in order to render the device complete and serviceable in every particular, all

as hereinafter set forth.

The present device is in the nature of an mprovement oi the door stop covered by United. Stat Letters Patent, No. 1,352,147, issued tome September 7, 1920, and the latch, of which mention has been made, is similar to that which forms a part of the previous invention.

The primary object of my invention is to provide a stop, of the class described, which is applicable for use in connection with a heavy swinging door, at the top of such door where said stop is out of the way, and which is capable of securely holding the door in open position, such stop being readily attached to almost any door casing and door, automatic in the engaging operation when the door is opened, and semi-automatic in the releasing operation when the door is closed, strong, and durable, convenient, and withal entirely practicable and highly eflicient.

This stop can be used in connection with a door that has no spring, or, in other words, with a door that is not self-closing, and will more frequently be employed with such a door than with one which is self-closing.

Another object is to provide a stop which specification of Letters Patent.

holds a door so safely and securely that the latter is not liable to he accidentally closed by the wind or other agency, but only with the hands and at such times as it may be desired to close said door.

I attain the objects and secure the advanof my invention by the means illustrated in the accompanying drawings, in which.

Figure l is an elevation of a door stop which embodies a practical form of my invent-ion (the same-being applied to a door casing and door), as viewed from the inside when the door is closed; Fig. 2, a side elevation of the parts and members disposed as in the first'view, a portion of the latch rod or bar being broken out to economize space; Fig. 3, a side elevation of the parts and members of the stop disposed as when the door is open, only the free terminal portion said latch bar appearing, however, and the door being misc space; Fig. 4, a bottom plan of the stop showing the members disposed as when the door is open, parts being broken out of the door casing, door, and latch bar, to save space as before; Fig. 5, an inside elevation the latch support and latch, and a cross section through the'latch bar and showing the lug thereon in looking engagement with said latch, these parts being disposed as in the two preceding views; Fig. 6, a bottom plan of the latch; Fig. 7, a top plan of the tree terminal portion of the latch bar showing the lug thereon, and, Fig. 8, a broad side elevation of the perforated portion of said latch support.

Similar reference characters designate similar parts throughout the several views.

In the general views fragmentary portions of a door jamb, a door lintel, and a door are represented at l, 2, and 3, respectiveiy. in Figs. 1, 2, and 3 the lintel 2 is shown in section, and in Figs. 2and 4 the door 3 also is shown in section. The jamb 1 appears in Fig. 2 wherein the same is in elevation, and in Fig. 4 wherein it is in section. The door is in elevation in Fig. 1, and 2 and 4. One of the hinges, by means of which the door 3 is connected with and supported from the jamb 1, is represented at 4 in Fig. 4:. 5

One element of this door stop is a, freelysuspended, swinging latch 55. This latch corresponds with one of similar construction which forms a part of the subject matomitted, in order to econo-.

7 end of said ter of the hereinbefore-mentionedpatent, and the same will be briefly described before entering into a detailed description of the new elements of the present stop.

The latchb has an arcuate bottom edge concentric with a bolt 29 which is the direct support and center upon which said latch swings. keeper 7.

p The bolt 29 passes rearwardly or inwardly through the latch 5 and a vertical support or hanger 8, and one side of said latch is contiguous with such hanger; The keeper 7 extends obliquely across the bottom 6, from the side of the latch 5 which is contiguous to the hanger 8 to. the opposite side of said latch, and a notch 9 is formed inthe outer or forward end of said keeper. The bottom of the keeper 7 is concentric with the bottom of the latch 5. The notched end of the keeper 7 may be termed the operating keeper, to distinguish it from the: end of the keeper which is contiguous tothe hanger 8. The keeper '7, with the is so constructed and .ar-

notch 9 therein,

6 that said tinged on. the latch bottom.

' keeper has ashort side .10 and a long side 11,

the former being the nearer to the hanger 8. Passing now to the new elements, it will be seen that a plate 12, is securely attached to the under side of lintel 2, and the hanger fi has a horizontal part 30 which is pivotally connected to said plate in such manher .as to enable said part and the hanger 2 plate 12, and permittedto'be'rotated pivotally connected with as awhole to swivel or turn upon and about the thus provided. In the present instance a lag-screw 13 is employed as the pivotal support for the hanger 8, the part 30 'being held in rubbing contact with the on the axis provided by said screw or pivot. The

lag-screw 13 passes upwardly through the part 30. into the plate 12. -Thelatch 5 is the hanger 8. beneath the horizontal part 00 thereof, by means of the bolt 29, as previously observed. The bolt 29 is held in place with the aid of a nut 14 which is on the inner, protruding terminal of said bolt, that is to say, the terminal of the bolt which extends beyond the inneror rear face of said hanger. The nut 1 1 must not, of. course, be tight enough to preventthe latch 5 from oscillating freely and by gravity on the bolt 29. The plate 12 mayin soinecases be omitted. There is an spring 17 has its inner On this arcuate' bottom 6911s. a

panded or otherwise arranged to engage the inner or rear face of the hanger 8, so as to prevent said spring from being thrust forwardly out of said hanger and so becoming detached therefrom. The plunger 18 has at the outer end a head corresponding end of the spring 17 is attached. The parts are so proportioned that normally the plunger 18 is disposed with a portion thereof forward of and a portion thereof behind the hanger 8, as best shown in Fig. 2. V i

horizontal latch rod or bar 21 is slidingly arranged in the horizontal, bottom part oftheslot 15 in the hanger 8, and said bar has on top rear end thereof a lug 22 which'is capable of passing through the vertical, upper part ofsaid slot. The outer or front terminal of the bar'2l is pivotally connected at 23 with an. angular bracket 24 secured to the inside of the door 3. At the inner end of the bar 21 is a depending lug 25. The latch 7 is normally in the path of the lug. 22, and the rear end ofthe plunger 18, which end protrudes behind the hanger 8, is in the path of the lug 25. Thelug 22 is preferably of the shape shown in the drawings and more especially in Fig. 7, in order to facilitate engagement of said lug with the latch keeper 7. As here presented the lugs 22 is arranged obliquely on the latch bar 21, and the narrower, vertical edges of said'lug are angular to provide beveled. surfaces for the more convenient contact with the keeper 7.

YJhen the door 3 is closed, the latch bar 21 is approximately at right angles to said door and extends some little distance beyond the back side of the hanger 8, the latter is approximately at right-angles to the jamb 1, and the latch 5 hangs vertically-see Figs. 1 and 2. But when the door is opened, the bar 21 is drawn outwardly with said door, the hanger 8 swiveling or turning on the pivot 13 to enable this to be done. The same relative angular position of the bar and hunger with attached latch is maintained, and always the same, but the bar now forms an obtuse angle with the door, and the hanger is no longer at right-angles to the jamb 1. The bar 21 is longenough 20 to which the.

and adjacent to the inner or terminal, as 19, ex-

to'enable the door 3 to be opened to its full extent, usually atan angle of. 4:5 degrees. is the door approaches its wide-open position the lug p. sses through the slot 15 and encounters the short side 10 of the keeper 7, with the: result that the latch 5 is rocked on its pivot 29, toward the jainb'l, in such a manner as to enable-said lug to enter-the notch 9; The part of the-lug 22 that first contacts with the keeper 7 is ihdicatedat 26 in Fig. 5,. and the part of said lug which on ters the notch 9 isrepresented at 27 in Figs. 1 and 7. Naturally the lug 22 is not of suflicient height to encounter the latch 5 above the keeper 7. Just before the lug 22 engages the notched end of the keeper '1, the lug 25 contacts with the rear end of the plunger 18 and forces said plunger forwardly against the resiliency of the spring 17. The parts are now disposed as shown in Figs. 3, a, and 5. The spring 17 tends to force the plunger 18 rearwardly, owing to which fact and the further fact that said plunger is bearing on the lug 25, the bar 21 with the door 1 is urged rearwardly or inwardly, and consequently the lug 22 is held in engagement with the notched end of the keeper 7. The door 3 cannot be closed because the latch 5 with its keeper is interposed between the lug 22 and the hanger 8. Any movement of the door 3 inthe direction to open the same wider is overcome by the spring 17, acting through the plunger 18 and the lug 25 on the bar 21.

To unlock or release the door 3, push it open a little farther, exerting suhicient force to overcome the resistance of the spring 17, so as to cause the lug22 to pass out of the notch 9 and beyond the keeper 7. Then the door is pushed into closed position, the lug 22, which wasfirst actuated forward, now moving backward with the bar 21. As the lug 22 moves rearwardly, it bears first with the edge surface 32, Fig. 7, on the side 11 of the keeper 7, as the latch 5 swings down from the position it occupies in. Fig.5 and certain of the other views, and forces said latch into a tilted position in the opposite direction, said latch swinging on the pivot 29 in a l cases. he soon as the lug 22 passes rearwardly beyond the keeper 7, t is latch 5 swings back into its normal, vertical position, as represented in Figs. 1 and 2. The lug 22 has passed through the slot 15 in the hanger 8 and some distance beyond said hanger by the time the door is completely closed. Meanwhile the lug 25 passes away from the plunger and is finally located at a considcmble distance from the same. During the inward travel of the bar 21 the hanger S swings on the pivot 13 until said hanger assumes the normal or former position and is finally in approximately parallel relationship with the closed door. a The bar 21 causes the hanger 8 to swivel as said bar is moved forward and backward through said hangs, otherwise, that is, if the hanger were stationary, the parts would bind i. d be inoperative. The spring 1'? acts to thrust the plunger 18 rearwardly as soon as the latter is released by the lug 25. The stop is now ready for a repetition oi"? the locking opera tion when the door is again opened.

The hanger 8 supports both the latch 5 and in part the latch bar 21. When the door is closed by far the greater portion of the bar projects rearwardly from the hanger 8,

and sai d bar is supported at all times by said hanger and the bracket 24. The bolt 23 passes downwardly through the horizontal part of the bracket 2 and through the bar 21 to receive a nut 28 on the lower, protruding terminal thereof. The nut 28 directly supports the outer terminal of the bar 21 from the bracket 24:, and must be loose enough to permit said barto oscillate on the bolt 23.

The bar 21, of a member that is flat in cross section and therefore better adapted for my purpose than would be a bar or rod oi some other shape in cross section.

The bottom of the keeper 7 is arcuate like the bottom of the latch 5 and concentric therewith, so that said latch can swing with said keeper quiteclosely to the bar 21 with out contacting therewith.

Although this stop is designed more especially for use with a door that has no spring and is not, therefore,. self-closing, it can be emp'loyedwith a door of the selt-closing type, as hereinbefore observed or intimated. y More or less change in the shape, size, construction, and arrangement oi. some or all of as herein presented, consists the parts of the door stop may be made with out departing from the spirit or my invention or exceeding the scope of what is claimed.
